Today I read one more story about pop-ups getting past our blocker (though I saw no pop-ups at either of those sites) and decided that given the recent spate of these claims, it was worth trying to do something about it. We are still #1 when it comes to defeating unwanted pop-ups, but we'll have to keep a close eye on the enemy if we're going to stay ahead. So if you're using the latest nightly branch builds of Firefox and you see pop-ups happening that you didn't request, please visit Bugzilla bug 253831 and provide information about the site where you saw the problem. If we find there are new and common techniques that are getting around our blocker, we'll try to seal off those avenues of attack.
